IMPROVEMENT IN PORTABLE WATER-HEATERS FOR DOMESTIC PURPOSES.

Specification forming part of Letters Patent No. 134,120, dated December17, 1872.

To all whom it may concern:

Be it known that I, JOHN S. WOOLSEY, of Gilroy, Santa Clara county,State of Californa, have invented an Improved Portable Heater; and I dohereby declare the following description and accompanying drawing aresufficient to enable any person skilled in the art or science to whichit most nearly appertaius to make and use my said invention orimprovement without further invention or experiment.

The object of my invention is to provide an improved portable heater orboiler by which water can be heated for household purposes; and itconsists mainly in a novel method of constructing the heater, anduniting the dinerent parts so that it is easily made tight withheads ofthe boiler. The front head D and the flue-sheet O are grooved in theproper manner to receive the ends of the inner shell 13, which are setinto their respective grooves in lead or other suitable cement, and thewhole is thus drawn tight by suitable bolts f. The two shells A and Bare brought together at their lower edges, and at this point are unitedby rivets, leaving an open space, over which the grate G lies, as shown.The heads D and E of the boiler are fitted to the outer shell A, asshown, and a wrought-iron band, H, is shrunk over the junction at eachend, so as to hold all the parts firmly together without rivets, and atthe same time make it steamtight. Suitable. gagescocks are provided forthe front boiler-head. A pipe, I, arises from the top of the boiler, andbranches off as shown at J J. These branches have cocks K, which areconnected by levers L, so that when one is opened the other will beclosed. One of these branches leads off the heated water, and the otherleads into the top of a barrel or tank, which is so placed as to havethe pipe M, from the bottom of the boiler, lead into thebottom of thetank.

Whenever the water is heated in the boiler, and when it is not neededfor heating pur" poses, a circulation will be kept up between it and thetank, so that all the water will become heated, and when, by reason ofuse, the water in the boiler is lowered, that from the tank will flow inand take its place. As this water is already heated, no cessation of thework need result. It affords a convenient method of utilizing the wasteheat and preventing any accumulation of pressure within the boiler. Thewhole device is cheap and effieient.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. The boiler having the shell B fitted into the heads 0 and D andsecured by the bolts F, substantially as and for the purpose described.

2. The shell A fitted to the heads D and E, in combination with thesecuring-bands H, substantially as and for the purpose described.

3. The pipes J with their double cocks K and operating-levers L, and thepipe M, when employed to form a connection with a tank or barrel, andoperating substantially as and for the purpose herein described.

' 4. A boiler composed of the double shells A and B, secured asdescribed, and having the pipes J and M with the cocks K andoperating-levers L, the whole forming a water-heating' apparatus,substantially as and for the purpose described.

In witness whereof I hereunto set my hand and seal.
